ISI Certification (BIS) for
Geotextiles Used in Subsurface Drainage Application IS 16393 in India

BIS CERTIFICATION FOR GEOTEXTILES USED IN SUBSURFACE DRAINAGE APPLICATION IS 16393 : 2015

In drainage, the geotextiles act as a conduit for liquids or gases. For under-drains constructed along pavements, the gravel-filled trenches lined with geotextiles allow water to drain into the trenches and separates or restricts soil materials.

Introduction to Indian Standard IS 16393 : 2015;  Geotextiles used in Subsurface Drainage Application

·       IS 16393 : 2015 cover  Geotextiles used in Subsurface Drainage Application. This standard specifies requirements for two classes of geotextiles used in drainage application such as subgrade dewatering, road base drainage and structure drainage by placing the geotextile against the soil to allow long-term passage of water into a subsurface drain system retaining the in-situ soil.

Class 1 geotextiles are for applications where applied stresses are more severe, that is, very coarse shape angular aggregate is used, compaction is greater than 95 percent of maximum density as per IS 2720 (Part 15) or depth of trench is greater than 300 mm.

Class 2 geotextiles are suitable for drainage applications which are less severe, that is, smooth graded surfaces having no sharp angular aggregate, compaction is less than or equal to 95 percent of maximum density as per IS 2720 (Part 15).

Woven slit film geotextiles (that is, geotextiles made from yarns of a flat, tape-like character) shall not be used.

·       IS 16393 : 2015 specifies the quality parameters or characteristics of the  Geotextiles used in Subsurface Drainage Application as follows :

(i)           Type of geotextile
